Abstract

The invention relates to a lighting system for at least one light-emitting means ( 24 ), in particular for light-emitting diodes, comprising a light fixture ( 22, 43, 61 ), in which the light-emitting means ( 24 ) and mechanical components like a housing, cooling element, reflector, etc. are located; comprising a convertor ( 23 ) for operating the light-emitting means ( 24 ); comprising an operating unit ( 10 ) having a charge storage ( 11 ), like a smart phone, for example, for changing a mode of operation of the lighting system ( 20 ), wherein in a first mode of operation, light is emitted across a first light exit surface by the lighting system ( 20 ), and in a second mode of operation, light is emitted across a second light exit surface, wherein the first light exit surface and the second light exit surface have different light emission characteristics.

First claim

What is claimed is:

1. A lighting system for at least one light-emitting means ( 24 ) comprising light-emitting diodes, comprising:
a light fixture ( 22 , 43 , 61 ), in which the light emitting means ( 24 ) are located;
a converter ( 23 ) for operating the light-emitting means ( 24 ); and
an operating unit ( 1 ), having a battery ( 11 ) for changing a mode of operation of the lighting system ( 20 );
wherein the lighting system can operate in at least a first mode of operation and a second mode of operation, and in the first mode of operation, light is emitted across a first light exit surface by the lighting system ( 20 ), and in the second mode of operation, light is emitted across the second light exit surface, and further wherein the first light exit surface and the second light exit surface have different light emission characteristics; and
wherein the at least one light-emitting means comprises light emitting diodes and when changing the mode of operation from the first mode of operation to the second mode of operation, a part of a first group of light-emitting diodes ( 42 , 62 , 55 ) is deactivated and/or a second group of light diodes ( 42 a , 62 a , 54 ) is activated, and the first group of light-emitting diodes ( 42 , 62 , 55 ) has a light emission characteristic for extensive emission for lighting a room and the second group of light-emitting diodes ( 42 a , 62 a , 54 ) has a light emission characteristic of focused light that is controlled to emit in one specific direction, and, the specific direction of the focused light is controlled by the operating unit through the control of at least one of a controllable light-emitting diode, a controllable reflector and a controllable lens.

2. The lighting system according to claim 1 , wherein the second group of light-emitting diodes ( 42 a , 62 a , 54 ) emits invisible light in the infrared range.

3. The lighting system according to claim 1 wherein the operating unit ( 10 ) is configured to transmit commands to the converter ( 23 ) via wired or wireless transmission.

4. The lighting system according to claim 3 , wherein the direction of the focusing of the light is dependent on a locating signal.

5. The lighting system according to claim 4 , wherein the converter ( 23 ) has means for locating ( 21 ) to focus the light on the locating signal.

6. The lighting system according to claim 5 , wherein said means for locating ( 21 ) determines the position of the operating unit.

7. The lighting system according to claim 6 , characterized in that the focusing of the light brings about a charge of the battery ( 11 ) of the operating unit ( 10 ).

8. The lighting system according to claim 7 , wherein the operating unit has means to charge the battery ( 11 ) through light in the form of one or several photovoltaic cells ( 13 ).

9. The lighting system according to claim 8 , wherein the operating unit ( 1 ), with a full charge of the battery ( 11 ), automatically sends out a command to deactivate the second mode of operation.

10. The lighting system according to claim 9 , wherein the operating unit ( 10 ), in case of a low charge state, automatically sends out a command to activate the second mode of operation.

11. The lighting system according to claim 10 , wherein the operating unit ( 10 ), in case of a large number of light fixtures, selects the light fixture ( 22 , 43 , 61 ) closest to the operating unit ( 10 ) to change the mode of operation.

12. The lighting system according to claim 11 , wherein besides changing the mode of operation, the operating unit ( 10 ) sends additional commands to the lighting system.

13. The lighting system according to claim 1 wherein the operating unit is a smart phone.

14. A method for operating a lighting system for light-emitting diodes, the method comprising the steps of:
providing an operating unit ( 10 ) that is a smart phone having a battery ( 11 );
using the smart phone to select the mode of operation of the lighting system ( 20 );
if a first mode of operation is selected, emitting by the lighting system ( 20 ), light across a first light exit surface;
and if the second mode of operation is selected, emitting light by the lighting system ( 20 ) across a second light exit surface, wherein the first light exit surface and the second light exit surface have different light emission characteristics; and
wherein when changing the mode of operation from the first mode of operation to the second mode of operation, a part of a first group of light-emitting diodes ( 42 , 62 , 55 ) is deactivated and/or a second group of light-emitting diodes ( 42 a , 62 a , 54 ) is activated, and the first group of light-emitting diodes ( 42 , 62 , 55 ) has a light emission characteristic for the extensive light emission for lighting a room and the second group of light-emitting diodes ( 42 a , 62 a , 54 ) has a light emission characteristic of focused light that specifically emits in one direction, and, the direction of the focused light is controlled by controlling at least one of a controllable light-emitting diode, a controllable reflector and a controllable lens.

15. The method according to claim 14 , wherein the operating unit ( 10 ) transmits commands to the converter ( 23 ) wirelessly.
